I have progressed to getting the upload_config.py to work for me. The roadblock was installing tftpy; thank you to @raf1110 for the key instruction at 27 Jan 2024 02:49

I have HBS860H drivers with 57HBS30 stepper motors (including encoder feedback to driver). I was getting very 'rough' and non-repeatable motor rotation although the hybrid driver-to-motor feedback wasn't indicating a missed step, so I wished to investigate the step/dir signal provided by the Remora EC300 to the driver. I hadn't fully understood the DMA conversation but I saw the significance of the Step Length/Step Space/Dir Hold/Dir Setup definition by Scott here 17 Nov 2023 05:35

, thank you. These values were intended for DM860H stepper drivers. I adopted these values and now have a 'normal' feel and sounding stepper motor; a big step forward.
The issue that remains is that the '12800 pulses/rev divided by 5 mm/rev equals 2560 pulses/mm' does not produce the correct degrees of rotation. I have to suspect still the 'Step Length/Step Space/Dir Hold/Dir Setup' values as these are 'borrowed' from another driver type.
This video decribes the drivers and provides the 'best' datasheets (similar Leadshine HBS86H)
Is there a conservative set of values that is likely to work well as a starting point, as just blindly increasing all 4 values may not be appropriate?
